The new Leeds United owner admits he is yet to forge a solid business relationship with the Whites' owner.
The Italian businessman, whose takeover of Leeds was ratified in April 2004, has earned a reputation in football for being somewhat impatient after sacking six managers in his 25-month reign at Elland Road so far.
Surely working under such a ruthless owner can bring its own insecurities for every staff member on the Leeds payroll, but Mansford has quipped that he is happy to have lasted a month under the 59-year-old.
Mansford only joined United in June after three years as Barnsley's CEO, and the young executive has admitted that he is yet to build a solid working relationship with Cellino.
Asked on LUTV what his relationship with Cellino was like, Mansford laughed and responded: "Yeah it's good. I've lasted a month! I've got a clock!
"I'm still in an infancy of building up a relationship with him.
"Obviously at my former club I could speak very open and honest [to the chairman] because we'd worked together for three years and we knew each other really well."
Nobody at Leeds will be feeling the heat more than Garry Monk, who is the seventh manager bidding for Cellino's affections.
The 38-year-old, sacked by Premier League side Swansea City in December, will know that he is unlikely to last long at the Yorkshire club if Leeds' promotion prospects are not very promising in the opening few months of the campaign.
